What are the major advantages of IPv6?
These can be summarised as follows: Scalability: IPv6 has a 128-bit address while IPv4 has a 32-bit address. Therefore, IPv6 provides more IP addresses; IPv6 offers a 2128 space (3.4 x 1038 addresses). Such an address space is sufficient to allocate about 1030 addresses per person on this planet. Security: IPv6 includes security in its specifications. This includes information encryption and the authentication of the source from which the information is arriving. Plug and Play: IPv6 includes the plug and play mechanism to facilitate the connection of user equipment to a network. With the plug and play facility, network devices can connect to the network without the need of manual configuration and without the need of any servers, such as a DHCP server. Mobility: IPv6 provides more efficient and robust mobility mechanisms. More clear and optimised specifications: IPv6 has adopted the good practices of IPv4 and removed obsolete IPv4 characteristics.
